Abstract

The time dependence of flux patterns obtained on an untwinned YBa 2Cu3O7-δ single crystal showing the 'meandering instability' is observed at T = 65 K using magneto-optical imaging. When applying a reversed external field to a remanent state, along the front of invading antiflux, macrovortices or droplets of flux are formed, and eventually separate from the flux front in a spiral-like motion. The time-dependent behaviour of these macrovortices is investigated in detail.
